Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick.
2. Remove the dipstick, wipe it clean, and reinsert it.
3. Pull it out again to check the fluid level; it should be between the "full" and "low" marks.
4. Inspect fluid condition; it should be red and clear. If it's dark or smells burnt, proceed to change the fluid.
Safety Warning: Ensure the engine is cool before checking the transmission fluid.

3. Inspect Gear Shift Linkage

Sub-steps:
1. Locate the gear shift assembly inside the vehicle.
2. Visually inspect the linkage for any disconnections or damage.
3. If necessary, remove the console cover to access the linkage thoroughly.
4. Reconnect or replace any damaged components.

4. Test Brake Switch

Sub-steps:
1. Locate the brake switch, typically near the brake pedal.
2. Use a multimeter to check for continuity when the brake pedal is pressed.
3. If the switch is faulty, replace it with a new unit.

5. Inspect Transmission Control Module (TCM)

Sub-steps:
1. Locate the TCM, usually found under the dash or near the transmission.
2. Disconnect the TCM connector and inspect for corrosion or damage.
3. Using a multimeter, check for proper voltage and ground.
4. If the TCM is faulty, replace it with a new unit and reprogram it as necessary.
